European Commission Unveils First EU-Wide Data Center Energy Performance Snapshot, Reveals 6.4GW IT Capacity
April 17, 2026
The European Commission has taken a significant step towards greater transparency in the digital infrastructure sector by publishing its first aggregated dataset on data center energy performance under the Energy Efficiency Directive (EED). This initial disclosure provides a crucial, though incomplete, benchmark for understanding the environmental footprint of the EU's rapidly expanding data center industry, which underpins everything from cloud computing to artificial intelligence.
According to the newly released interactive dashboard, data center operators across participating member states reported a total installed IT power demand of 6.4 gigawatts (GW). This capacity, spread across 776 facilities, consumed 16.7 terawatt-hours (TWh) of energy. The data, covering reports from 2023 and 2024 across 18 countries, indicates a weighted average power usage effectiveness (PUE) of 1.36, a key metric for energy efficiency. Germany emerged as the bloc's largest hub, leading in both the number of data centers and total installed IT capacity. The report categorized 224 facilities as "large" data centers, constituting 28 percent of the reported market, while "very large" centers numbered only 52, making up 7.3 percent.
The Commission emphasized that this aggregated picture is not yet comprehensive, as participation from all EU member states is not complete. "The data the EC has aggregated so far under the directive does not include participation from all member states, or even necessarily complete data from the individual countries included," the report noted. Germany is cited as a frontrunner in implementation, having enacted its Energy Efficiency Act in 2023 to transpose the EED into national law, likely yielding more robust reporting.
This data release lays the groundwork for more stringent future policy. The Commission is preparing a comprehensive data center efficiency package for adoption in the second quarter of 2026. This package will include a full assessment of the reported data and introduce a pan-European rating scheme for data centers, for which a call for feedback was launched last month and runs until April 23. The package is also expected to propose minimum performance standards, signaling a move from voluntary reporting towards regulated efficiency benchmarks for the industry.
